I don’t think that her getting a 5/5 rating in the databook means that she at Itachi’s level of genjutsu. 2) Bee vs Edo Itachi, Bee states "genjutsu" when he sees Itachi turn into crows ch549. 6 – Kurenai.

Genjutsu (幻術, Literally meaning: Illusionary Techniques) is one of the main categories of jutsu which use chakra. This was seen when she fought against Itachi and Kisame, but her attack was reversed by Itachi… Genjutsu is most often used by ninja with very precise chakra control and very high intelligence, the most notable being Itachi Uchiha and Kurenai Yūhi. Itachi Uchiha (うちはイタチ, Uchiha Itachi) was a ninja of Konohagakure's Uchiha clan that served as an Anbu Captain.

I'm talkin about that moment when she tried to put Itachi under a genjutsu and kill him LOL, I mean there was no ninja in town that didn't knew the Solo King and his capabilities, let alone that he was from an Uchiha heritage and this is one of the main abilities of the clan. Kurenai Sarutobi (猿飛紅, Sarutobi Kurenai, née Yūhi(夕日, Yūhi)) is a kunoichi from Konohagakure and the leader of Team Kurenai. According to the Second Mizukage, genjutsu falls under the broad category of Yin Release. Kurenai is a natural Genjutsu user, and her special jutsu is the "Demonic Illusion: Tree Binding Death." Genjutsu are employed in the same fashion as ninjutsu, however, the effects of genjutsu are not real, being only illusions experienced by those who fall victim to it. Capable of discerning the truth in an luring and instant enemies to a place far beyond his genjutsu,most of her technique’s are focus around flora. I’m going to be honest and say what most people think; who is Kurenai again?

So she was planning on killing Itachi herself. His low lvl genjutsu reversed her greatest genjutsu.

As a child, Kurenai met Asuma Sarutobi during the Academy entrance ceremony and graduated at age 9.

When Itachi & Kisame came to the Leaf and Kurenai and Asuma tried to fight them off.

Alright, so this is just going to be a quick rant defending Kurenai given that apparently every youtube comment section seems to think it downright hilarious that Kurenai, a lowly Jonin, used genjutsu against Itachi Uchiha, otherwise known as the Christ-King of the Naruto universe according to the fandom. KuReNaI uSeD gEnJuTsU oN iTaChI! We can at least say from what we've seen, that Itachi's genjutsu is not unbeatable.

Itachi and Sasuke met face-to-face and, while exchanging genjutsu, had a conversation about the Uchiha, Madara, and Itachi's "true" motives of wanting to take Sasuke's eyes. I'm talkin about that moment when she tried to put Itachi under a genjutsu and kill him LOL, I mean there was no ninja in town that didn't knew the Solo King and his capabilities, let alone that he was from an Uchiha heritage and this is one of the main abilities of the clan. In otherwords he hasn't moved his body once in those scans. Consider that prior to Itachi's arrival, he was just revered as great. I want to invite users to discuss how powerful Itachi's genjutsu is. the full extent of Kurenai abilitie are predominantly Is all unknown, her skill with genjutsu is so extensive that it is said to rival even those of Uchiha Itachi. But wtf are y'all thinking comparing hers to Itachi's. Kurenai knew who she was up against but had no idea that he was a genjutsu specialist. 3) Kurenai biting her lip to get out of the genjutsu that Itachi reflected ch141. When a genjutsu is used on them, the user quickly decrypts the genjutsu with their Sharingan to understand how it works.

Well, she is Konohoa's best genjutsu user, and her abilities are in par with Itachi's known abilities (aka, mature sharingan, not including mangekyo) and she is probably a bit better.

The most commonly seen Genjutsu is simple creation of phantasms- causing the targeted person to hear, see, smell, taste and feel things that are not actually there in order to manipulate them; other applications of Genjutsu are rare. Genjutsu (Illusion Techniques) are techniques that use the chakra in the victim's nervous system to create illusions; an advanced intellectual Ninjutsu. Alternatively, a genjutsu user can create relatively small differences in the environment, which is more effective for intel gathering.
